岩相法鉴定钢中非金属夹杂物的方法,又称工艺岩石学或冶金岩石学.本文提供了在岩相显微镜下,钢中非金属夹杂物的形态、颜色,偏振光效应、光性,以及借助折射系数的测定和微量定性的方法,对夹杂物进行定性分析来确定某非金属夹杂物属哪一种.通过对夹杂物的定性鉴定和对夹杂物的形态、分布的分析,我们可以鉴定出废品钢是由哪些夹杂物造成的,或者说明某个钢种性能发生变化的原因.
The method of identification of non-metallic inclusions in steel by facies method is also called process petrology or metallurgy petrology.This paper provides the morphological, color, polarized light effect, phototropism of non-metallic inclusions in steel under petrographic microscope, And by means of the determination of the refractive index and the qualitative analysis of the qualitative analysis of inclusions to determine which of a non-metallic inclusions which through the qualitative identification of inclusions and the analysis of inclusions morphology, distribution, we can Identify which inclusions are the cause of the scrap steel, or why the properties of a steel change.
